Summary

This is a single-group, within-subject, double-blind, double-dummy, placebo and active-controlled study evaluated whether the FDA-approved cannabinoid dronabinol (Marinol) would enhance analgesia, subjective reports, and cognitive performance when compared to the FDA-approved opioid hydromorphone (Dilaudid).

Detailed description

This was a human laboratory systematic examination of whether adding the FDA-approved cannabinoid dronabinol (Marinol; oral) to the FDA-approved opioid hydromorphone (Dilaudid; oral) would change the experience of hydromorphone as rated by laboratory measures of pain, subjective reports of drug effects, and cognitive performance. Subjects are healthy individuals with no history of drug use disorder. Study subjects and staff were completed blinded to the study drugs and the class of drugs under investigation and were informed that subjects may receive opioids, stimulants, cannabinoids, benzodiazepines, over the counter medications, and/or placebo. All participants completed all sessions. Sessions lasted up to 8-hours and were conducted at least 7 days apart on an outpatient basis. Primary outcomes were collected from participants prior to dosing and at several hour periods post-dosing.
